ROLLER-SUPPORT FOR EDGEWISE-MOVABLE DOORS- Specification of LettersPatent.

Patented Feb. 26, 1907.

Application filed August 7,1906. Serial No- 329,591.

To all whom it may concern.-

Be it known that we, GEORGE GEORGEN- SON and JOSEPH E. HENNEN, citizensof the United States, residing at Fond du Lac, in the county of Fond duLac and State of Wis consin, have invented a newand useful Improvementin ItoLer-Supportsfor Edgewise- Movable Doors, of which the following isa specification.

This invention is a sliding-door-operating device particularly adaptedfor box car doors.

It is characterized particularly by an operating-handle which isconvenient as a handle for pulling the door open or closed and also forshifting the rollers on which the door slides, so that when the handleis in idle position the shoes at the lower edge of the cardoor rest uponthe track on which the door slides, so that it will not accidentallyslide open; but when the handle is operated the rollers are pressed downupon the track to lift the door and shift the weight thereof onto therollers, so that the door will readily move.

A further feature of the invention is that the handle is located at thelower edge of the door in convenient positionto be operated by the handsof aman on the ground or by the foot of a man on a platform, and byhaving the rollers which su port the weight of the door at the bottom tereof if there should be any resistance it would be near the operator.Thus if the door catch or the track become obstructed it can be readilyremedied.

The invention is illustrated in the accompanying drawings, in which-Figure 1 is a side elevation, partly broken away, of a car-door providedwith the device with the door closed and the handle in inoperativeposition. Fig. 2 is a similar view showing the parts in operation andthe door partly open. Fig. 3 is an edge or end view of the door withadjacent parts of the car in section.

In the drawings the car-door is indicated at A, the floor at K, and theside of the car at L. On the side of the car, under the doorway, is atrack F. The door has at its lower corners shoes II, which fit over thetrack and serve as retainers and also rest in contact upon the track tosupport andhold the door when the opener is inoperative.

E indicates a handle-rod or bail which extends along beside the loweredge of the door and has inturned ends, which are pivotally.

mounted in small boxes D, set in recesses 1n the door, so that thehandle will swing down and out or up and in against the face of thedoor, as indicated in Fig. 3. The ends of the handle-rod are bent toextend outwardly through the boxes, and the projecting extremitiesbeyond the same have cam-lugs d, which bear upon the top of theverticallyswinging roller-frames 0, containing the rollers C, journaledtherein. The frames 0 are hinged at B to angle-irons b, which are fixedto the bottom edge of the door and are preferably made to extend aroundthe corner and part way up the edges of the door to strengthen the same,as indicated at b. The plates G on front and back of the. car-door formguides for the rollers and their frames and keep them in properposition.

' In normal position the weight of the cardoor bears the shoes H againstthe track and lifts the frames, the pressure of whose frames against thelugs d holds the handle swung up against the door. To open the door, thehandle is swung down, causing the lugs to bear down on the roller-framesand lifting the door, so that the shoes are raised from the track andthe weight shifted onto the rollers, and the door can then be rolledupon the track with ease by pull or push on the handle or closed bysimilar operation.

The convenience of position and manipulation of the handle gives an easeof operation superior to ordinarydevices and en'- ables the door to beset in any desired posi tion. The top of the door may be retained andguided by any suitable or known devices.

We claim- 1. The combination with a sliding door and a track, of shoeson the door, which normally rest upon the track, rollers which travel onthe track, frames hinged to the door and in which the rollers; arejournaled, and means to, bear down upon the frames to shift the weightof the door from the shoes to the rollers.

2. The combination with asliding door, of shoes at its lower edge, atrack upon whie the shoes normally rest and sup ort the door,roller-frames hinged at one on to the lower edge of the door, rollerswhich rest on the track and on which the frames are fnlcrumed, and ahandle pivoted on the door and hearing at its ends upon the frames,substantially as described.

3. The combination with a sliding door, of means to normally support thesame, a track under the lower edge of the door, frames hinged at one endto the said lower edge, rollers journaled in the frames and resting onthe track, and a bent lever-handle extending along beside the lower edgeof the door and pivoted to the door, and having cam-lugs at its endsbearing upon the frames and adapted by pressure on the handle to liftthe door and I 5 support the same on the rollers.
